Specification of Letters Patent. Application filed-February 4.190s. Serial no. 244 .251.

Patented June 5, 1906.

To all whom tam/my concern:

Be it known that we, WIL IAM-WILEY Som- BOROUGH and CHARLES EDWARD SoHULTz, citizens of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented new and useful Improvements in Pneumatic-Tire PI'OtGO-w tors, of which the following is a specification.

This invention relates to protectors for pneumatic tires; and the. object of the invention is to rovide a device of this character that may e easily laced upon or removed from the air-tube of the tire when deflated and which will be held securely in position on the tube when the latter is inflated without the use of any s ecial fastening devices.

A preferred f drm of the invention will be fully described hereinafter,vreference being had to the accompanying drawings, in which Figure 1 is a side elevation of a wheel, showing the protector in position u' on the Fig. 2 is a longitudinal section of aportion of the tire and protector on the line 2 2 of Fig. 3. Fig. 3 is a transversasection through the tire and rotector. Fig. 4 is a lan view of a portion 0 the protector, WhlOh Wlll be hereinafter designated the shield; and Fig. 5 is a perspective view of'a shoe, aseries of which are employed with the shield to form the protector. 'A represents a wheel, which may be of an preferred form of construction as to the hu and spokes and upon the rim (1 of which a gliifumatic tube 1) may be secured in any orary manner, said tube being provided with the usual inflating-valve c.

The protector consists of a shield d and a series of shoes e' The shield will preferabl be formed of comparatively thin metal, a thou h it may be of wood, and will be semicircular in cross-section to fit over and inclose the tube 6 preferably for more than half the circumference of the tube. The shield is provided with a series of slots or openings f in its peripheral portion, which slots may be any desired distance apart and are separated by the bars 9.

The shoes e, which may be of metal, wood, or any other suitable material, will form the traction-surface of the Wheel and are of such size as to project through the openings f in the shield. They are curved on their inner or lower surfaces to fit snugl on the air-tube b and 'are provided wit flan es h on opposite sides which lie under t e side 'portions of the shield, as clearly shown in Fig. 3, and with flan es'i on then other two 0 posite sides, which 'e under the bars 9 of t e shield, as clearly shown in Fig. 2. The outer or tread surface, ofthe shoes will also preferably be curved and may be corrugated or otherwise roughened to preg ent slipping of the wheel on wet or icy suraces.

The inner surface of the shield is also corrugated or otherwise roughened, as indicated by k inFi 3, to revent relative movement between t e air-tu ab and the protector after the tube is inflated.

In applying the protector the shoes e are inserted through the openings f of the shield and referabl they will fit snugly therein. The s 'eld an shoes are then fitted in proper position over the tube b, when the latter is deflated, and then the tube 1) is inflated, and the protector will thereby be held securely in position upon the tube. It is obvious that the shoes can be separately replaced when worn or broken and t at they and the shield thoroughly protect the tube against liability to puncture.

.Without limiting ourselves to the precise details of construction illustrated and described, We claim 1. The combination with the air-tube of a tire, of a'shield having a rou h inner surface fitted over and inclosing sai tube for more than half its circumference and provided with openings in its peri heral portion, and a series of shoes indepen ently su ported on the tube and projecting through t e openin s in the shield, said shoes having flanges whic lie between the tube and shield, and said shield being held on the tube by the inflation of the latter, substantiall as described.

2. The combination with the air-tube of a wheel-tire, of a shield, having a rough inner surface fitted over and inclosing said tube for more than half its circumference, and a series of shoes secured by the shield to the tube and projecting beyond the shield to form the traction-surface of the wheel, substantially as described. 3. The combination with the air-tube of a tire, of a shield fitted over the tube and having a mu h inner surface, said shield inolos- In testimony whereof we afiix our' signaing the tu e for more than half of its oircu ntures 1n presence of two witnesses. ference and being held on the tube by the mi Winn-{AM WILEY SCARBOROUGH.
